MOLDING DEVICE.

Specification of Letters latent.

Application filed February 3, 1920. Serial No. 356,041.

To all whom t may concern:

Be it known that I, EUGENE L. BAKER, a citizen of the United States,residing at Taunton, in the county of Bristol and State ofMassachusetts,-have invented a new and useful Molding Device, of whichthe following is a specification.

T he structure forming the subject matter or" this application is amolding device, and the invention aims to provide novel means wherebythe sand-carrying Jframes may be swung over onto the patterns, be swungott the patterns, and be swung together, thereby to complete the moldwithout lifting the sand-carrying frames bodily, either with respect tothe pattern frame or with respect to each other.

It is within the province ot the disclosure to improve generally and toenhance the utility ot devices of that type to which the inventionappertains. c

Jn the accompanying drawings Figure 1 shows in plan, a deviceconstructed in accordance with the invention; Fig. 2 is a sideelevation, showing the structure as it will appear after one of the sandtrames has been swung over on top of the other sand trame; Fig. 3 is asection taken approximately on the line 3-3 of Fig. 1 and showing one ofthe hinges; Fig. 4 is a section taken approximately on the line 4 -4 ofFig. 1, and showing another of the hinges; and Fig. 5 is a 'ragmentalplan disclosing a moditication.

in carrying out the invention there is prf)- vided a main or patterntrame 1, within which may be located plates 2 heldin place by set screws3, the plates 2 carrying patterns 4. The patterns 4 of one platecorrespond to one-halt of the object to be cast, whereas the patterns ofthe other plate correspond to the other haltz of the object to be heldon the although the expedicast. The patterns may be trame 1 in anydesired way, plates 2 and the set screws 3 are an ent means to this end.

The invention comprises a pair of sand trames 5 and 6 disposed end toend and located along one side ot the pattern traine 1. The constituentparts of the sand Jframes 5 and 6 may be made to open, the said parts otthe trames being connected by hinges 7 and by hooks 8 adapted tocoperate with keepers 9.

The sand frame 5 is vconnected with the 11 on the pattern frame l, andhooks 12 on the frame 5. The irst hinges which connect the frame 6 withthe Aframe 1 may be in the form of ears 14 on the respective trames,theears being united by pivot pins 15. The

V ends of the frames 5 and6 are connected by second hinges 16 formed, ifdesired, like the hinges 10-12 The trames 5 and 6 and the pattern plates2 may be provided with interengaging elements 17, in the form of pinsand openings, adapted to prevent relative lateral movement between theframes 5 and 6 on the one hand, and the trame 1 on the other hand, whenthe frames 5 and 6 are swung over on top of the trame 1 as hereinafterdescribed.

In practical operation, the frames 5 and 6 are swung together, on thehinges 10-12 and 15-14, on top of the frame 1 and the pattern plates 2.rlhe sand is then rammed into the frames 5 and 6. The frames 5 and 6then are swung ofi the frame 1 on a pallet 30, shown in Fig. 2. Theframe 5 is swung on the hinges 16 on top of the frame 6. The frames 5and 6 then are opened at the hinges '7, and the complete mold, clearedfrom the frames 5 and 6, is carried away to the point of casting. It isto be observed that since the hinges which connect the frame 5 with theframe 1 are of the forni shown in Fig. 3, the frame 5 will bedisconnected automatically roin the frame 1 when the 'frame 5 is swungover on top O'li the frame 6.

At times, it may be desirable to effect the casting operation while thesand is inclosed within the frames. Then, referring to Fig. 5, thetrames, such as the frame 6a are fashioned solid, the hinges 7 beingomitted. After one of the sand frames has been folded over on top of thesand frame 6LL in Fig. 5, the frame 6a is disconnected from the patternframe 1n. To facilitate this operation, the hinges 25 of Fig. 5,corresponding to the hinges 14.--16 oi Fig. 1, are constructed like thehinges 10-12 of Fig. 3.

The various hinges hereinbefore alluded to may be constructed in avariety of ways, the object in view being to permit, iirst, the frames 5and 6 to be swung over on top of the frame 1 and, second the frames 5and 6 have been swung olf the frame 1 to permit Patented May 11, 1920.

the frame 5 to disengage itself automatically from the frame l and topermit the frame 5 to be swung over on top of the frame 6.

The Construction of the device is such that the work incident tohandling the various frames lis cut down appreciably. Under the oldprocedure7 the frames 5 6 were first lifted bodily upon the frame' l,then lifted bodily off the frame l and finally lifted one on top of theother. The structure shown in .the drawing, therefore, does away withthree lifting operations calling for the ex- ,penditure of considerablestrength.

Having thus described the invention, what is Claimed is In a device ofthe class described, a pattern frame; .a pair of sand frames; firsthinges uniting the sand frames with the pattern frames whereby both sandframes may be swung on top of the pattern frame and beswung off thepattern'frame, one of the first hinges comprising separable partswhereby one sand frame may be swung on top of the other sand frame afterbothsand frames have been swung off the pattern frame; and a secondhinge connecting the sand frames and permitting one sand frame to beswung on top of the other sand frame as aforesaid. l

In testimony that I claim the foregoing as my own, I have hereto afIiXedmy signature Y in the presence of two witnesses.
